1 Claim.

My invention relates to improvements in scissors, shears, or the like,whereby the manual operation of scissoring or shearing is rendered moreefficient and easy, and accurate, with considerably less effort than isrequired for the same operations in using conventional shears.

Important objects and advantages of my invention will be apparent from areading of the following description and the appended drawing, whereinare shown preferred embodiments of my invention for illustrativepurposes.

In the drawing:

Figure 1 is a general side elevational view of a scissors or shears inaccordance with the present invention.

Figure 2 is an opposite side elevational View of a slightly modifiedform.

Referring in detail to the drawing and first to the embodiment shown inFigure 1, which is generally designated by the numeral 5, the numeral 6designates the usual screw pivot which connects the scissors or shearblades I and 8 in overlapping relation, the blades having handles 8' and9, respectively, extending on the opposite side of the pivot. Inordinary scissors or shears the cutting edges 10 and II of therespective blades are substantially straight, whereas in the presentinvention these edges are divergently curved at an angle of divergenceranging from one degree to 35 degrees and as high as 40 degrees, and thehandles 8' and 9 are similarly divergently curved at a similarangulation to that provided for the cutting edges l and II. In addition,the shoulders l2 and [3 at the juncture of the handles with the bladesat the handle side of the pivot 6 are cut away at a sufficiently sharpangle and to a sufficient extent to permit the full closing or occlusionof the terminal portions of the cutting edges l0 and II by closing thehandles 8' and 9.

By reason of the arrangements described the cutting action can begin atthe very inner terminals of the cutting edges I0 and H where theleverage factor of the handles 8 and 9 is greatest. Further, the cuttingaction acts with substantially increased power over ordinary shears orscissors right along the cutting edges I0 and II as far as the terminals[4 and I of these cutting edges as the handles are brought together,correct angulation of the cutting edges obtaining for most eflicientcutting and easy operation throughout the entire length of the cuttingedges as the handles are brought together.

In the modified formshown in Figure 2 of the drawing both of the handlesBa and 9 are not completely divergently ofiset as in the case of theabove described embodiment, but the handle 9 is curvedly displacedsomewhat toward the handle 8a, while the cutting edge IOa of the blade1a corresponding to the handle 9 has the same divergent curvature withrespect to the cutting edge II a of the blade 8a. Further, thearrangement of shoulders such as the shoulders l2 and I3 is eliminatedby having the blades 8 a and la strictly in side by side arrangement,with the terminals 150, and I ia both pointed or leafshaped instead ofhaving the terminal M of the first described embodiment angularlytruncated as indicated by the numeral 14. The arrangement of the seconddescribed embodiment provides in a slightly modified type of shears, theessential features of operation and efiicient mechanical advantageprovided for in the first described embodiment.

Although I have shown and described herein preferred embodiments of myinvention, it is to be definitely understood that I do not desire tolimit the application of the invention thereto except as may be requiredby the scope of the subjoined claim.

Having described the invention, what is claimed as new is:

Shears or the like constructed with a departure from the normal byhaving the blades thereof curved longitudinally for the full length ofthe blades; said blades being curved away from each other in oppositedirections from the pivotal point of the blades toward the terminals ofthe blades whereby, upon closing of the blades in initiating a cuttingaction such cutting action will begin immediately at the point of thepivotal connection of the blades so that the cutting edges of the bladesfor the full length thereof are availed of in effecting the cuttingoperation, the handles of the shears having divergence with respect toeach other similar to the divergence of the blades.
